Our family loves June (and calls her by name). The sweet potato preset is spot on, and my mother loves to eat one for breakfast. The suggestion is 2 part:
1 - timer option to start/finish a preset at a given time i.e. we could place a sweet potato in the June the night before and suggest a time for it to start/finish baking. This would also be useful for crock pot cooking.
2 - the app allows starting June at a given temp - but not starting a given preset.
